TIMOTHY GINGRAS, OF BUFFALO, NEW YORK.

BELTING.

SPECIFICATION forming part of Letters Patent No. 385,613, dated July 3,1888.

Application filed October 27, 1887. Serial No. 253,488. (No model.)

To all whom if; may concern:

Be it known that I, TIMOTHY GINGRAS, of the city of Buffalo, in thecounty of Erie and State of New York, have invented a new and usefulImprovement in Belting, of which the following is a specification.

This invention relates to that class of belting in which cotton or othertextile fabric is combined with leather.

My invention has the object to construct an improved bolting of thiskind which will not stretch unequally or shrink, which will permit theuse of a large proportion of cotton or other fabric, while at the sametime possessing the strength and durability of leather belting, andwhich can be manufactured at less expense than leather belting.

. shifter.

The invention consists of the improvements which will be hereinafterfully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view ofasectionof my improved belting. Fig. 2 isa longitudinal cross section thereof.Fig. 3 isa perspective viewof a modified construction of the belt.

Like letters of reference refer to like parts in the several figures.

The body or main portion of the belt is composed of cotton or othersuitable textile fabric, A, which is made of a width corresponding tothat of the desired belt.

13 represents a series of longitudinal re-enforcing strips ofleather,which are secured to the outer side of the belt by stitching, riveting,or other suitable means. I prefer to se cure the same by two rowsofstitches, as shown. Two of these reenforcing strips are preferabl yarranged at the longitudinal edges of the belt, so as to protect theedges thereof from wear by the action of the forks of the belt- Theother strip or strips are located between these marginal strips, oneintermediate strip being shown in the belting represented-zj in thedrawings. A greater or less number of these intermediate strips isemployed, according to the width of the belt.

The reenforcing strips B prevent to a large extent the cotton or fabricfrom stretching, and what little stretching does take place in the beltis equally distributed among the several strips, thereby causing allparts of the belt running of the belt at all times.

to stretch uniformly and insuring the straight These men forcing stripsalso prevent the fabric from shrinking and causing damage to the machiirery, which sometimes occurs when the belt is exposed to a moistatmosphere.

The spaces between the leather strips B are filled by strips of cottonor other fabric, G, whose upper edges stand flush with the adjacentleather strips, as shown in Fig. 1, and which are secured to the body Aby stitching, cementing, or otherwise.

When the belt runs around an idler or tightener pulley, and the locationof the pulley is such as to require the side of the belt having thestrips to run in contact with the pulley, it is found in practice thatthese filling-strips are desirable, as they enlarge the contactsurfaceof the belt, and thereby increase its transmitting effect. They alsoprevent sagging of the belt between the leather strips and theconsequent slipping of the belt. If desired, 110wever, thesefillingstrips may be omitted, as represented in Fig. 3; but I prcfertouse the same, as they render the belt more efficient, and the additionalexpense is comparatively small.

An important advantage of my improved belt is the convenience with whichjoints can be made in the same. This is accomplished by simply cuttingaway a portion of the fabric at one end of the belt and on one sidethereof, so as to allow the ends of the leather strips to project beyondthe fabric, as shown in the upper portion of Figs. 1 and 3, and bycutting away an equal portion of the leather strips at the opposite endof the belt and on the opposite side thereof, as shown in the lowerportion of Figs. 1 and 3, so as to let the fabric project beyond theleather strips. The two ends of the belt are then brought together, as

shown in Fig. 2, whereby the abutting ends of ables a jobber or largeconsumer to keep on lOO hand a whole roll of belting, and to constructan endless belt (as smooth-joint belts are known in the trade) withoutrequiring the services of the manufacturer.

My improved combination-belt can be produced at less cost than anordinary leather belt, as narrow strips of leather can be employed. Ithas been found by repeated tests that the belt is stronger than aleather belt of the same size.

I am aware that fabric belts have been provided at their longitudinaledges with a strip of leather or other suitable material for receivingthe wear of the shifting-fork and preventing the fraying or raveling ofthe fabric; but this construction permits the belt to stretch unevenlyand to sag between the marginal wearing-strips under the lateralpressure of the shifting-fork, thereby bringing portions of the belt outof contact with the face of the pulley and reducing thetransmitting-power of the belt.

I do not wish to claim in this application the construction ofthejoint,which is described and claimed in my pending application, No. 254,148,filed November 3, 1887.

I claim as my invention 1. The combination, with the body of the belt,composed of cotton or other textile fabric, of marginal strips extendingalong the longitudinal edges of the belt, and one or more longitudinalleather strips arranged between said marginal strips, substantially asset forth.

2. The combination, with the body of the belt, composed of cotton orother textile fabric, of a series of leather re-enforcing stripsextending lengthwise of the belt, and fillingstrips of cotton or othertextile fabric arranged in the spaces between said re-enforcing strips,substantially as set forth.

WVitness my hand this 20th day of October, 1887.

TIMOTHY GINGRAS.
